Well, we have something like 20 or 25 VME machines controlling
experiments here, some with only 16Mb of RAM. The lifetime
of these systems is often of the order of 20 years (we shall
finally get rid of our TMS9900 processors with 32kB in November,
they were bought in 1982 I believe).
So yes, I object strongly object if I don't have a way
of removing useless PMAC code. The kernel is already very
bloated compared with the 2.2 we started with, which was
well below 1MB with the minimal setup: serial console, root
on NFS, no swap, some locally modules to control the PCI<->VME
bridge and what is behind on the VME bus.
